            Hello,

for a costumer i have replaced there old small home router with this cisco 886.

i get a ip adres in the dialer from the isp , and i have internet connection.

everyting works except it is VERRY SLOW if i check the internet connection speed it is 0.49 Mbps down and 0.42 Mbps up (speedtest.net)

normaly i would get almost 4 Mbps download !

i have checkt with Belgacom (isp) the cabel and everyting is ok ! (with the previos router full speed internet! )

some portion of the config is included !

i tryed to put encapsulation on the atm aal5snap and aal5mux .... no diffrens...

i see my vdsl is connectec with DS channel0  4640 ... so the hardware speed is ok ..

Try updating VDSL FW to

vdsl.bin-A2pv6C035j

any help with that pleas, did not do that before ....

i need a service contrac to download this file.... i am a partner but i have no service contract.. kan you zip it to me ?

Sorry, I'm not allowed to redistribute Cisco software.

is there a other posibility why it is so slow ?

why is there nog pppoe connection ? but i have internet access.

As mentioned before, usually it is due to bugs in DSL firmware, sometime IOS bugs.
